a corporation or New Jersey I Application October 7, 1932, Serial No.636,658 I 2 Claims; (01. 1242-119) f- This invention relates to reelssuch as are used for supporting cords and particularly cords com; posedof twisted paper strips.

Twisted paper cord and vegetable parchment twisted cord such as isdescribed in my companion application Serial No. 636,659, filed October7, 1932, are usually made on machines of which the one known in thetrade as the Watson ma chine is a typical example. In such a machine thepaper strips are twisted into the cord formation and are wound on alarge spool. From this large spool the cord is generally unwound intoballs of cord whereupon the large spool is.

replaced in the twisting machine whenever. said 1 machine is ready forthe installation of another spool. These spools are very substantial andexpensive and remain in effect a part of thetwisting machine. Rewinding,of course, involvesmachinery and labor. Under. theseconditions itoocurred to me to investigate whether it might not be possible to createa reel of great cheapness, yet sufficiently rugged to properly positionand hold the cord in placeas it was manufactured by the twisting machineso that it might be possible to send the filled, reel directly to thecustomer without any rewinding, the customer throwing away the reelwhenthe. cord has all been unwound therefrom. I have found that, within.the

limits imposed bythe problem, it wouldbe pos-- sible to accomplishsucharesult andlthe reel which is the result, is-the subject matter of thisapplication.

The reel is illustrated in the accompanying drawing, in which Fig. l isa side view partly in section; Fig. 2 is a cross section on the line 22of Fig. 1; Fig. 3 is an end view of the spool; and Fig. 4 is a detailview of a modification.

In the drawing A designates two end flanges or discs of the reelcomposed of heavy cardboard or pressed wood, each provided with acentral opening to receive and seat the metal collar B, B.

The collar B, B is constituted of a thin strip of bendable tin or ofequivalent metal said strip being bent around the'end of the core C andpositioned, in the finished reel, in tubular form in the apertures ofeach of the end discs A.- The tin strip is provided with a flangeportion B parallel with the exterior faces of the discs A abuttingagainst said flanges and. overlying the edges of the apertures of thesaid discs A, while the tubular part B which has a minimum width whichis considerably greater than the thickness of the discs A and may begreater than several thicknesses of such discs, hugs the inner peripheryof the apertures of the discs A and lines the inner peripheryof saidapertures. A cardboard tube or core C fofappropriate thickness andlength is supported in close contact with the inner periphery of thetubular metal section 13" having an outside diameter approximately thesame as the diameter of the apertures of the discs A, so that when theparts are assembled they are all jammed tightly together. The tinsleeves B are prickpunched or in part depressed into the body of thematerial constituting the core C at several points as indicated at D tohold the several parts in place against axial displacement of thesleeves or outward displacement of the discs A, at least during the timethat the core is wound on the reel in. the ,twisting machine. It ispreferred 79 that one of the prick-punches, D shall be made at the pointwhere as indicated in Fig, 1 the end edges of the tin sleeves B meet orwhere they may slightly overlap. Instead of prick-punching the tinsleeve B may be grooved as indicated at D in Fig. .4. The inner edge ofthe tubular metal section B' may also be-initially bent slightly in adirectiontoward the tube C so as, as indicated at B. in Fig. 4,,tosecure additional anchorage between ,the sleeve B and the tube C whenthe 8 partsare finally assembled.

'I'hefirst round of cord holds the tin collar in place so that-itisthereafter impossible for the collar or theends of the reel to come offthe core ortube in the process of winding or of handlingthereel a fter ihas been filled. Twisted paper cord is made and wound on spools or reelsat a time when the paper as such is not free from moisture, but thoughthe paper be quite wet, the strength of the new reel is such as tomaintain its structure notwithstanding the strains which the presence ofmoisture and subsequent evaporation entails.

A twisting machine is generally provided with driving mechanism forrotating the reel at a rate corresponding to the rate of formation ofthe twisted cord. Such mechanism contacts with the inner surface of thespool and in the case of the new reel with the inner surface of the coreor tube 0 near the ends of the spool. 1'00 The prick-punching andgrooving of the metal sleeve B should therefore be limited so as not tohave the metal of the sleeve passthrough the tube wall so as tointerfere with the proper positioning of the driving elements of thema-v chine. When a reel such as has been described has been filled onthe twisting machine it is removed therefrom and replaced by anotherreel of the same character. Reels so filled are shipped I directly tothe consumer, who, mounting them 1'10 to fit any of the standardtwisting machines and may be made in larger or smaller sizes appropriateto the arts in which paper cord is used.

The manufacture of such reels is exceedingly simple and inexpensive. Thesimple and inexpensive character of the reel makes it possible to marketthe product without rewindingvv and also supplies the consumer with amore convenient and attractive support for his supply of, paper cordthan he has thus far been able to obtain. v

I claim:

disc aperture and thecore having unconnected ends extending around thecore in the form of a sleeve, having portions thereof depressedinto thebody of the core to resist axial movement of the sleeve relating to saidcore, said sleeves having outwardly flaring end flanges adjacent to andencircling the ends of the core, the outer circumferential surface ofsaid sleeves being parallel with the outer surface of the core and withthe walls of the disc apertures, and the diameter of the disc aperturesbeing approxi mately the same as the outside diameter of the sleevedcore so that the discs if moved from one end of the reel to the otherwill encounter no obstruction'save the end flanges, said centrallyapertured end discs being positioned on said sleeves adjacent to saidflanges and held inposition at right angles to the axisof the core bythe parallelism of the walls of the apertures and the circumferentialsurfaces of themetal sleeves and by the abutment of the side walls ofthe discs against the flanges of the sleeves, 'eachof said sleeves beingconsiderably greater in width than the thickness of the end discs andextending into the path of the cord to be wound on the reel so that thecord when wound'on the core and upon the sleeves will tightly hold thesleeves in position on the core and the sleev es" thus held will, incoordinationwith the "cord wound on the reel, effectivelyprevent allrelative 1 of a sleeve,"said sleeves" having outwardly flaring endflanges adjacent to-and encircling the ends 1. A reel for cord,comprising a heavy tubular paper core, a centrally apertured end discateach end of the core, the walls of the apertures of the discs beingparallel with the outer sur-'" face of the core, and a thin pliablemetallic strip intermediately situated between the wall of each ,of thecore, and a thin pliable metallic strip intermediately situated betweenthe wall of each .1 disc aperture and the core, having unconnected endsand extending around the core in the form of the'core, the outercircumferential surface face of the core and with the walls of the discapertures and the diameter of the disc apertures being. approximatelythe same as the outside diameter of the sleeved core so that the discsif moved from one end of the reel toithe other will encounter noobstruction save the end flanges, said centrally apertured end discsbeing positioned on said sleeves adjacent to said flanges and held inposition at right angles to the axis of the core by the parallelism ofthe walls of the apertures and the circumferential surfaces. of themetal'sleeves and by the abutment of the side walls of the discs againstthe flanges of the sleeves, each of said sleeves being in part depressedinto the material constituting the core to resist axial movement of thesleeve relatively to the core, one portion at least of said depressedportions occurring at the meeting end parts of the strips of which thesleeves are formed, and each of said sleeves being considerably greaterin width than the thickness of the end discs and extending into the pathof the cord to be wound on the reel so that the cord when wound on thecore and upon the sleeves will securely fasten the sleeves in positionon the core and the sleeves thus heldwill, in coordination with the cordwound on the reel, effectively prevent all rela- 12c tive movementasbetween the core, the sleeves and the end discs, and will cause the enddiscs to be held on the core so that they can no longer bemovedinwardlyon' the core or be separated therefromduring the withdrawalof cord from 5 the'reel inthe use of the reel.
